however, the cases were most probably tuberculosis, it was recom- 
mended that the use of milk for human consumption be discon- 
tinued, and that one of the affected cows be slaughtered for further 
examination. 
Experiments in protective inoculation in anthrax and swine fever 
have been continued, and recently some investigations have been 
made in reference to the effects of inoculation with pure lymph 
taken from the lungs of the cattle affected with pleuro-pneumonia. 
The results up to the present lead to the conclusion that when the 
lymph is perfectly free from septic organisms no irritation nor other 
local or constitutional effects are produced, even when the inoculat- 
ing fluid is introduced into parts of the body which are considered 
to be dangerous localities. 
Numerous morbid specimens from cattle, sheep, and swine have 
been received at the College, including tuberculous deposit in lungs, 
liver, and other organs ; hydatids in lungs and liver of cattle and 
sheep ; and actinomycosis in the glands in young cattle. 
The district veterinary surgeons have reported serious losses 
among lambs from rheumatic swellings of the joints (joint ill), asso- 
ciated with inflammation of the umbilical cord (navel ill), in various 
parts of the country. 
Investigations are now being carried on at the College in refer- 
ence to the organisms of pleuro-pneumonia and swine-fever, horse- 
pox and cow-pox in regard to their relation to each other, and also 
in the effects of a new disinfectant which promises to be of some 
value as a preventive in contagious diseases of farm stock.

1. Mr. J. A. Pearson, of Compton, Winchester, sent on 
March 17, 1890, a sample of undecorticated cotton-cake*, which he 
described as bought as "pure," 41. 10s. per ton ex mill. He had 
made a contract for 20 tons with Messrs. Dixon & Cardus, Limited, 
Northam, Southampton. The analysis below was returned on 
March 22, 1890 :— 
Moisture 1675\ 
Oil 5-90 
1 Albuminous compounds (flesh-forming matters) . 16 69 joq.qq 
Mucilage, sugar, and digestible fibre . . . 33-14 r 
Woody fibre (cellulose) 22-97 - 
Mineral matter (ash) 4f)5/ 
1 Containing nitrogen . . . 2 67 
The cotton-cake is not a pure cake, and contains an admixture of cereal 
husk and starch. It contains an excessive quantity of moisture.
